Yeah the Hex can be no fun - If you are having trouble holding the steering wheel straight I saw another writeup where they tied a loop around the bottom spoke of the wheel with a tie down strap or similar and then tie a loop you can step your foot into to hold it straight. Essentially it allows you to hold the steering wheel with your feet and use both hands to try to crack the bolt. I also had a small section of pipe (actually a section of the handle of my jack) that I used for extra leverage on the breaker bar.
